The lecturer in the
Department of Electronic Engineering and Communications (Professor Dr.
Dhirgham Kamal Naji) published a single scientific research entitled: In the Journal Progress In
Electromagnetics Research Letters, Vol. 149, 165-176,
2024 Which is classified
within Scopus containers with an impact factor (CiteScore) of 2.7 and within the
third quarter. In this paper, two new types of dual-band antennas are
presented: a plane wave (CPW)-fed fractional monopole and an asymmetric planar
strip (ACS)-fed fractional monopole. These antennas are designed to operate in
two distinct bands suitable for WiMAX 3.5/5.5 GHz and WLAN 5.2/5.8 GHz
applications. Both antennas have self-similarity by using semicircular and
quarter-circular folded rings, respectively, which represent the radiation
elements of the antennas. Two simulation programs are used to extract the
simulation results of the reflection coefficient, gain, efficiency, and
radiation patterns. Prototypes of the two designs are fabricated. The
simulation results of the reflection coefficient agree well with the
experimental results, demonstrating that the two antennas perform well in the
above applications. Moreover, the achieved peak gain values are greater than
2 dBi, the efficiency exceeds 90%, and the radiation is quasi-omnidirectional
in both bands. To view the research, please visit the following link:Compact Dual-Band Monopole Antennas with Fractal-Based Half- and Quarter-Circular Folded Loops for WiMAX and WLAN Applications
